• Opinion dynamics is the development and analysis of dynamical models that capture how individuals in a social network interact and exchange opinions.

Automated Planning

Also known as AI planning, is the process of finding a sequence of actions that will transform an initial state of the world into a desired goal state, given the world model.

Key elements: Goals, Actions, States, Constraints
